The NTSB's narrative final · quoted from the NTSB record
The 12,500-hour pilot reported that during final approach to the airport, the flaps were extended to the full-down position. Subsequently, the airplane decelerated and rolled uncontrollably to the left. The pilot regained control of the airplane and landed without incident. A post-flight inspection of the airplane by the crewmembers revealed that the left inboard flap had separated and the attach bolts were still in the flap attach brackets. Examination of the left inboard and outboard flap actuator fittings (parts number JW121-8L and JW121-6R) revealed visible evidence of fatigue and corrosion on the surface of the inboard fitting.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number FTW04IA128.
